Hi Kim I just did the same switching from gre to vxlan. Here's what I learned:
You have to delete all the old networks in the installation that where created with gre. They do not work because the tunnel type is stored in the DB. I was not able to change it. According to ovs-neutron_plugin.ini. I think this depends on the distribution used. I realized, that not all daemons read the same config files on startup. Thats why I had also to modify both mentioned files. To ensure all parameteters are set, I used debug=True and verbose=True like this you see the configuration the daemon uses in the logfile. hope this helps Benedikt On 28.05.2014 04:32, BYEONG-GI KIM wrote: > Hello. > > I followed the installation guide for OpenStack Icehouse, and the > installation was completed successfully; Two Instances could ping with > each other through GRE unnel. > > After that, I've tried to modify the Networking from GRE to VXLAN by > following the Configuration Reference > described > http://docs.openstack.org/trunk/config-reference/content/networking-plugin-ml2_vxlan.html > > Although I modified all the parameters like "type_drivers", > "tenant_network_types", "vni_ranges", etc. and restart all the related > services on the every nodes, the VXLAN network doesn't work fine at all. > First, I could not add an additional network on dashboard.
